Introduction to VLT 2800

VLT®2800 Series
■General warning
The voltage of the frequency converter is
dangerous whenever the converter is con-
nected to mains. Incorrect fitting of the
motor or frequency converter may cause damage to
the equipment, serious injury or death. Conse-
quently, it is essential to comply with the instructions
in this manual as well as local and national rules and
safety regulations
■These rules concern your safety
1. The frequency converter must be disconnected
from the mains if repair work is to be carried out.
Check that the mains supply has been discon-
nected and that the prescribed time has passed
before removing motor and mains plugs.
2. The [STOP/RESET] key on the control panel of
the frequency converter does not disconnect the
equipment from mains and is thus not to be used
as a safety switch.
3. The unit must be properly connected to the earth,
the user must be protected against the supply
voltage and the motor must be protected against
overloading pursuant to prevailing national and lo-
cal regulations.
4. The earth leakage currents are higher than 3.5
mA.
5. Protection against motor overload is not included
in the factory setting. If this function is required,
set parameter 128 Motor thermal protection to
data value ETR trip or data value ETR warning.
For the North American market: The ETR func-
tions provide overload protection of the motor,
class 20, in accordance with NEC.
6. Do not remove the plugs for the motor - and
mains supply while the frequency converter is
connected to mains. Check that the mains supply
has been disconnected and that the prescribed
time has passed before removing motor and
mains plugs.
7. Note that the frequency converter has more volt-
age inputs than L1, L2 and L3 when the DC bus
terminals are used. Check that all voltage inputs
are disconnected and that the prescribed time
has passed before repair work is commenced.
■Warning against unintended start
1. The motor can be brought to a stop by means of
digital commands, bus commands, references or
a local stop, while the frequency converter is con-
nected to mains. If personal safety considerations
make it necessary to ensure that no unintended
start occurs, these stop functions are not suffi-
cient.
2. While parameters are being changed, the motor
may start. Consequently, the stop key [STOP/RE-
SET] must always be activated, following which
data can be modified.
3. A motor that has been stopped may start if faults
occur in the electronics of the frequency con-
verter, or if a temporary overload or a fault in the
supply mains or the motor connection ceases.
195NA139.10
Warning:
It can be extremely dangerous to touch the electrical parts
even when the mains supply has been disconnected.
Also ensure that other voltage inputs are disconnected
from load sharing, for example (sharing of DC intermediate
circuit). For VLT 2800: wait at least 4 minutes.

■Control unit
On the front of the frequency converter there is a
control panel.
The control panel is divided into four function groups:
1. Six-digit LED display.
2. Keys for changing parameters and shifting display
function.
3. Indicator lamps.
4. Keys for local operation.
All displays of data are in the form of a six-digit LED
display capable of showing one item of operating
data continuously during normal operation. As a
supplement to the display, there are three indicator
lamps for indication of mains connection (ON), warn-
ing (WARNING) and alarm (ALARM). Most of the
frequency converter’s parameter Setups can be
changed immediately via the control panel, unless
this function has been programmed as Locked [1]
via parameter 018 Lock for data changes.
■Control keys
[QUICK MENU] allows access to the parameters
used for the Quick menu.
The[QUICK MENU] key is also used if a change to a
parameter value is not to be implemented.
See also [QUICK MENU] + [+].
[CHANGE DATA] is used for changing a setting.
The [CHANGE DATA] key is also used for confirming
a change of parameter settings.
[+] / [-] are used for selecting parameters and for
changing parameter values.
These keys are also used in Display mode for se-
lecting the display of an operating value.
The [QUICK MENU] + [+] keys must be pressed at
the same time to give access to all parameters. See
Menu mode.
[STOP/RESET] is used for stopping the connected
motor or for resetting the frequency converter after a
trip.
Can be selected as Active [1] or Not active [0] via
parameter 014 Local stop/reset. In Display mode,
the display will flash if the stop function is activated.
NB!:
If the [STOP/RESET] key is set at Not ac-
tive [0] in parameter 014 Local stop/reset,and
there is no stop command via the digital inputs or
serial communication, the motor can only be
stopped by disconnecting the mains voltage to the
frequency converter.
[START] is used for starting the frequency converter.
It is always active, but the [START] key cannot over-
ride a stop command.
■Manual initialisation
Disconnect mains voltage. Hold the [QUICK MENU]
+ [+] + [CHANGE DATA] keys down while simultane-
ously reconnecting the mains voltage. Release the
keys; the frequency converter has now been pro-
grammed for the factory setting.

VLT®2800 Series
■Display readout states
Display mode
In normal operation, one item of operating data can
be displayed continuously at the operator’sown
choice. By means of the [+/-] keys the following op-
tions can be selected in Display mode:
- Output frequency [Hz]
- Output current [A]
- Output voltage [V]
- Intermediate circuit voltage [V]
- Output power [kW]
Menu mode
In order to enter the Menu mode [QUICK MENU] +
[+] must be activated at the same time.
In Menu mode, most of the frequency converter
parameters can be changed. Scroll through the pa-
rameters using the [+/-] keys. While scrolling in the
Menu mode proceeds, the parameter number will
flash.
The display shows that the setting in parameter 102
Motor power PM,N is 0.75. In order to change the
value of 0.75, [CHANGE DATA] must first be acti-
vated; the parameter value can then be changed
using the [+/-] keys.
If for a given parameter the display shows three dots
at the right, it means that the parameter value has
more than three digits. In order to see the value, ac-
tivate [CHANGE DATA].
The display shows that in parameter 128 Motor ther-
mal protection the selection made is Thermistor trip
[2].
Quick menu
Using the [QUICK MENU] key, it is possible to
access the 12 most important parameters of the fre-
quency converter. After programming, the frequency
converter is in most cases ready for operation.
When the [QUICK MENU] key is activated in Display
mode, the Quick menu starts. Scroll through the
quick menu using the [+/-] keys and change the data
values by first pressing [CHANGE DATA] and then
changing the parameter value with the [+/-] keys.
TheQuick menu parameters are:
•Par. 102 Motor power PM,N
•Par. 103 Motor voltage UM,N
•Par. 104 Motor frequency fM,N
•Par. 105 Motor current IM,N
•Par. 106 Rated motor speed nM,N
•Par. 107 Automatic motor adaption.
•Par. 204 Minimum reference RefMIN
•Par. 205 Maximum reference RefMAX
•Par. 207 Ramp-up time
•Par. 208 Ramp-down time
•Par. 002 Local/remote operation
•Par. 003 Local reference
Parameter 102 - 106 can be read out from the mo-
tor’s nameplate.
■Hand Auto
During normal operation the frequency converter is
in Auto mode, where the reference signal is given
externally, analog or digital via the control terminals.
However, in Hand mode, it is possible to give the ref-
erence signal locally via the control panel.

VLT®2800 Series
On the control terminals, the following control signals
will remain active when Hand mode is activated:
•Hand Start (LCP2)
•Off Stop (LCP2)
•Auto Start (LCP2)
•Reset
•Coasting Stop Inverse
•Reset and Coasting Stop Inverse
•Quick Stop Inverse
•Stop Inverse
•Reversing
•DC Braking Inverse
•Setup Select LSB
•Setup Select MSB
•Thermistor
•Precise Stop Inverse
•Precise Stop/Start
•Jog
•Stop Command Via Serial Comm.
Switching between Auto- and Hand mode:
By activating the [Change Data] key in [Display
Mode], the display will indicate the mode of the fre-
quency converter.
Scroll up/down in order to switch to Hand mode:
When the frequency converter is in Hand mode the
readout will be like:
and the reference can be changed by using the fol-
lowing keys:
NB!:
Please note, that
parameter 020 may block the choice of mode.
Automatic motor tuning
Automatic motor tuning (AMT) is performed as fol-
lows:
1. In parameter 107 Automatic motor tuning select
data value [2]. “107”will now flash, and “2”will
not flash.
2. AMT is activated by pressing start. “107”will now
flash and dashes will move from left to right in the
data value field.
3. When “107”appears once more with the data
value [0], AMT is complete. Press [STOP/RE-
SET] to save the motor data.
4. “107”will then continue to flash with the data
value [0]. You can now proceed.
